    Duoetto 12 volt water heater-gctid368718

    I'm not sure if you can get these in 110 volt or not but I'd think they will eventually have to make a 110v unit.I have fitted these to RV'S and they work well.I paid $399 with with a shower head and lockable case.Easy way to add a shower

    On 12 VDC you would need quite a battery system to run it. Note the 25 amp draw.

      yes that's true but only takes about 20 mins with the generator[240v] to get hot and mixed with cold water it give us about 30 litrers of shower water.I only use the 12 volt if the boat is running.Would be ok if you have solar panels also.

        The math is tough to justify. I must echo the comment that you would need to tow a barge full of batteries to make this work.

        Why not just get a Solar Shower (they actually work very well) or a Zodi propane fired shower? I have used both and they work great.

        Solar panels?? No way, no how - sorry. You would never be able to recharge what you've used by solar alone.

          OOOPS Sorry Yes you're correct [wasn't thinking of 25 amp bit but just the 12 volt ]

          Do you think that it is to much for the alternator to cope with ?

          if I had a 100ah battery and ran it for 1 hour would that mean it would use a quarter of the batteries power?

          Would it use more or less battery power in 12 volt mode or 240volt mode through an inverter?

          Just asking for curiosity ,we mainly plan to run it with the generator.

          Thanks Dave

            Sorry, I can't understand why, if you have to run the engine, you wouldn't just have a heat exchanger water heater? Makes no sense to me.

              If the engine is running, why should you need the 12v? Is your boat an outboard?

                All the heat exchange units I looked at where not recommended for salt water once I got to read the manuals.I have not fitted this unit to the boat as yet[my new to me one is still in Florida] so I'm all ears for better ideas .We do go out to some islands and stay a few days at a time diving etc so I won't always be running the boat hence I thought of using a generator an hour a day to top up batteries ,heat the water and let the cook use whatever she deems a necessity .This worked for off road camping etc so I thought I do the same with the boat.

                The engine cooling is a raw water set up in a 2355 ciera 5ltr poverty pack LOL.

                The unit won't go to waste as I own a caravan park so I can use it else where so all ideas are appreciated.

                Thanks Dave

                  If you are gonna run your engine in salt water raw water cooled, a $400 water heater is the least of your worries!

                    is this what I need to start with?

                      I would say that or something similar. What is the water temp where you will be boating? That will have a lot to do with the size nd type heat exchanger you need.

                      The ones that work extremely well in the Pacific Northwest seem to be marginal in Florida for example.

                      I'm assuming the boat has never been run in the salt?

                      I've been told that if it has there is no point in converting because of something I didn't understand

                      good luck
